This invention relates to a collapsible box and to a cardboard or likeblank from which the box is constructed.

The object of the invention is to provide an improved or simplifiedconstruction of collapsible box or display device of the type providedwith a bottom, front, back and side walls and two lateral flaps orpanels for display purposes standing in the plane of the front of thebox. 7

According to the invention, a box provided with a bottom, front, backand side walls and lateral flaps or panels as aforesaid is constructedfrom a single blank which comprises a part adapted to form the back wallof the box and two lateral wings adapted to fold into the planes of thesides of the box and provided with extensions to form the aforementionedflaps or panels, the front wall of the box being formed by a part whichis cut out of one of the aforesaid lateral wings so that it remainsattached to that wing by means of the aforesaid extension thereof and isbrought forward with that extension when the wings are folded into theplanes of the sides of the box. The bottom of the box is formed by athird wing which proceeds from the part out out from one of the firstmentioned wings as aforesaid and is bent back when the said out out partis brought forward. The third mentioned wing has two lateral extensionsadapted to be folded so as to lie against the side walls of the box whenerected and one of these lateral extensions serves to cover the openingwhich would otherwise be left at one side by reason of the part out outtherefrom t form the front wall of the box as aforesaid. The thirdmentioned wing may also have an extension adapted to be folded so as tolie flat against the back wall of the box when erected. The blank mayalso be provided with a fourth wing for display purposes proceeding fromthe top edge of the part which forms the back of the box. This wing maystand in the same plane as the back of the box when erected or it may befolded forwards or backwards as may be desired.

The invention is illustrated in the accompanying drawings in which:

Figure 1 is a plan of a blank,

Figure 2 is a front elevation of a box made from the blank shown inFigure 1.

Figure 3 is a side elevation of the same box,

Figures 4 and 5 are a plan and edge view respectively of the box shownin Figures 2 and 3 when collapsed,

Figure 6 is a View similar to Figure 1 showing a slightly modified formof blank, and

Figure '7 is a side elevation of a box made from the blank shown inFigure 6.

The blank shown in Figure '1 consists of a single piece of cardboard orother suitable material cut from a fiat sheet. It comprises a part Iadapted to form the back wall of the box, and two lateral wings 2 and 3adapted to fold into the planes of the sides of the box and providedwith two lateral extensions 4 and 5 intended to form flaps orpanels fordisplay purposes.

In order to. form a front wall for the box, a cut is made along the line6 so as to cut out from the parts I and 3 afront wall part 1 havin a tabTo which part 1 remains attached to the rest of the wing 3'by means ofthe extension '5 thereof. The blank has a third wing 8 which extendsdownwards from the part 1, this part 8 being intended to form the bottomof the box. Two lateral extensions or flaps 9 and I0 and a downwardextension or flap II proceed from the wing 8 as shown. A fourth wing H!which proceeds from the top edge of the part I is provided for displaypurposes.

The blank is intended to be folded along the lines shown as brokenlinesin Figure 1 and the blank may be treated in any known manner tofacilitate folding along these lines.

For the purpose of making a box from the blank shown in Figure 1 it isnecessary to attach the front wall part 1 to the wing 2. To enable thisto be done, the wing 2 may be folded upon the part I so as to bring thefold line between the parts 2 and 4 upon the fold line at which the tabla is attached to the part I. The tab may then be fastened to the part 2by means of staples l3 (Figure 4). This may be done as part of theprocess of manufacture of the blank.

In Figure 5, the part I is shown displaced somewhat from the plane ofthe part I and the part 4 is shown folded back upon the pant Z. This isdone merely for clearness of illustration, however, and in practice thepart I may remain in the same plane as the parts I and 3 and the part 4may lie fiat upon the parts I and 3 so that there will not be more thantwo thicknesses of material at any part of the folded blank. Thecompleted blanks may be packed in this condition.

pulled forwards so that the parts 2 and 3 are pulled into the planes ofthe sides of the box. The part 8 is then folded back to form the bottomof the box, the flaps 9, l0 and H being tucked up inside the box. Theflaps I I! and Il serve to cover the opening which would otherwise beWhen the box is to be erected, the part I is left at one side of the boxand at the back of the box by reason of the fact that the front wallpart 1 is cut out from the back and side wall parts I and 3.

The blank shown in Figure 6 of the drawings is generally similar to thatshown in Figure 1 and corresponding parts are marked with the samereference numerals. The difference between the form of blank shown inFigure 6 and that shown in Figure 1 is in the fastening means providedfor attaching the front wall part 1 to the part 2. In the form shown inFigure 6, the front wall part 1 is formed with a tab 1b and a slit 1c isformed at the foldline between the parts 2 and 4 so that the tab 1b canbe pushed through the slit 7c. The tab is formed with ears Id andsuitable slits 1e are formed in the part 2 of the blank to receive theseears.

The tab lb and the slits To and Te form a releasable fastening which caneasily be fastened by the user when the box is erected. There istherefore no need to bring the parts 2 and 1 together until the box isto be used. The blank shown in Figure 6 may therefore be laid out fiatas shown in Figure 6 for transit and storage.

The blank shown in Figure 6 is erected to form a box in the same manneras that shown in Figures 4 and 5 except that the fastening of the parts2 and I together is carried out as part of the process of erecting thebox. For this purpose, the tab 1b is pushed through the slit 1c and theears Id are then tucked into the slits 1e as shown in Figure '7.

The shape of the line 6 along which the part I is cut out may be variedas desired so as to give the front wall of the box a straight top edgeor an edge of decorative shape such as that illustrated in the drawings.The parts 4, 5 and I2 may also be cut to decorative shapes as may bedesired.

The boxes shown in the drawings are of greater width than depth fromfront to back and consequently the cut-out.part I necessarily extendsinto the back wall part I. In some cases, however, the depth of the boxfrom front to back may be so much greater than the width of the box thatthe front part 1 is cut out of the side wall part 3 only, the back wallpart I being left intact.

I claim:

A cardboard or like blank adapted to form a box, consisting of asingle piece of material cut from a flat sheet and comprising a part toform the back wall of the box, two lateral wings foldable into planes toform the side walls of the box and provided with extensions to formlateral flaps at the front of the box, a part partially cut out of aportion of the blank which includes at least one of said lateral wingsand along a line which defines two edges of the front wall but leavessaid cut-out part attached to said lateral wing along a line which joinsthe latter to the extension thereof, said cut-out part being foldablealong its line of attachment to said lateral wing into a forward planeto form the front wall of the box when the lateral wings are foldedrelatively to the back wall forming part-into the planes of the sides ofthe box, a third wing attached to said cut-out part and bendablebackwardly to form the bottom of the box, and extension means on saidthird wing foldable upwardly within the box to cover the opening lefttherein by removal of said cut-out part.

2. A blank according to claim 1, wherein said cut-out front wall formingpart is formed with a tab for fastening it to one of said side wallforming lateral wings.

3. A blank according to claim 1, wherein said cut-out front wall formingpart is formed with a tab, and the blank has a slit cut therein adjacentto one of said side wall forming lateral wings to receive said tab andthereby fasten the front wall forming part releasably to the respectiveside wall forming wing.

4. A collapsible box made from a blank according to claim 1, whereinsaid front wall forming part is permanently fastened to both side wallforming wings, one of said side wall forming winigs being stapled tosaid front wall forming par FREDERICK HERBERT LOWE.
